I refer to your email of 18 September 2019 in which you outlined your concerns with my response to your request for information of 21 August 2019.
I have responded to each of your questions below.

1. The speed limit at the location the sign is installed

This is as per the speed limit at the location the sign was installed, listed in column G of the spreadsheet I sent to you on 18 September 2019.

2. The date the speed limit was set (though given your caveat listed, I am assuming
this is just the installation date for all of the devices)

All speed limits were set prior to the electronic signs being installed.

50km/h speed limit came into effect prior to the Council having delegated speed limit setting powers. These were set by central government.

They originated in 1930 as 30mph limits and were metricated in 1974. They were reconfirmed though the WCC Speed Limit Bylaw part 6. The link to the Bylaw is in the previous response on 18 September 2019.

The excell spreadsheet has been updated with dates for 30km/h.

3. The date that the sign was configured with the current speed (again, assuming this
is the installation date given the caveat listed)

The date the electronic sign was configured to the current speed is the same date that the signs were installed.

4. If the configured speed does not match the current speed limit, then a timeframe on
when the council is planning on correcting the configuration to reflect the actual speed limit.

I refer you back to our response of 18 September 2019. All electronic signs were checked and recalibrated as necessary last December, the Council found that 14% of the electronic speed signs needed to be reconfigured and this work has been completed.

5. Whether the above policies (in regards to installation of the sign, or changing of the
speed limit) were followed when the sign was installed. If they were not followed, then what is the council doing to ensure that the policies are followed in the future.

I refer you back to our response of 18 September 2019. The Council follows the guidance set out by NZTA. To ensure that the guidance is followed the Council conducts routine maintenance on the electronic speed signs, and repairs faults when report by Council staff, Contractors and Public as and when required.

6. Also, your date format is a bit confusing, does Aug 18 mean 18th August 2019, or
just at some point in August 2018? I'm happy not having a day, but it is a bit confusing.

The date format in the excell spreadsheet is in Month-Year format. The road speed limit was set first. When the electronic signs became available to use, they were installed. This was done at a much later date the hence the difference in years.

The second half of your request will be responded in a separate email, this will be sent shortly.
